Part 1

You're John Henry Eden's prisoner... but are you really? As this mission begins, Colonel Autumn is removed from your cell at the request of Enclave President Eden, and Eden then has your cuffs removed so that you're free to walk. Oddly, even though you were a prisoner in a prison cell, all of your goods that were previously in your inventory are in the locker straight ahead near the doorway, which you can go through after you get all of your goods back (be sure to reequip a weapon and your armor!) Once outside, an Enclave officer will intercept you. It doesn't really matter (as far as karma is concerned) how you deal with him. You can try to convince him of a number of things, or you can simply talk crap to him, which will result in hostilities. We gunned him and his Power Armor-clad friend down in cold blood before proceeding. What's the problem? After all, these guys took you as prisoner. Turn the tables while you still can.

You're now free to explore the floor your cell was on. You're not going to find much of anything of interest on this floor as far as good or items are concerned, but you will certainly run into a few Enclave soldiers and scientists, both of which you should kill with relative immunity (our Automatic 10mm was wreaking havoc on Power Armor-wearing enemies, while the scientists are vulnerable to just about any kind of attack). Ultimately, however, when you've finished combing this initial floor for enemies (and picked their bodies clean of goods), you're free to seek out the staircase leading to the floor above.

On this floor, everything will change. While soldiers on the previous floor were passive to you, attacking only if you attacked even if you already killed some of their brethren, the fact remains that your situation won't be the same up here. This is the kitchen and cafeteria area, and when you arrive, you'll hear Colonel Autumn literally override President Eden's previous orders to let you come see him without any issues. Now, Enclave enemies will shoot on sight, which makes your rampant killing of their personnel much less offensive. Nonetheless, seek out the kitchen up here and kill the enemies guarding it and any residuals within it. Then, raid it for goods. Apart from the ridiculous amounts of food within (Cram, Dandy Boy Apples, Fancy Lads Snack Cakes, Potato Crisps and more), you'll also find ammunition (10mm Rounds, Energy Cells, Electron Charge Packs, et cetera) and other incidental items, from Metal Cooking Pots to Pilot Lights, as well as Stimpaks, RadAway and more in the two medical kits on the side of the locker.

After stocking up on what you can, head back into the eating area and seek out the door leading upward to the floor above (you'll have to climb up two staircases). When you arrive at the door at the top of the second staircase, press through to the adjacent room. This is Raven Rock Level 2 (the entire complex being wholly known as Raven Rock). The next few paragraphs will cover level 2 (which is built primarily around the 2-monikers you'll find everywhere, whether they have C, B or A next to them. You'll work in reverse order, through C, then through B, and finally into A. Start with A, however, scouring the labs you encounter for goods, including a Conductor, a Hot Plate, and even some curative items, like Rad-X and Mentats. And keep your gun at the ready! Hostile Enclave Soldiers and the defenseless scientists they're guarding could be around any corner. Gun anyone you see down, as you're running out of areas in the main quest to gain much-needed experience.

The B series of labs will have more of an orange hue to them, as opposed to an overbearing blue glow. Here, many more items can be found, and there are more enemies to gun down as well. Be sure to search both levels of any given floor when you find them (you can usually scour areas underneath the metal gratings that make up the floors of most area if you can find staircases leading down -- just beware of traps). When you reach an area with many lockers lined in a semicircle with a nearby staircase, you know you're heading in the right direction. Ammunition galore and other items (like Fission Batteries and Cartons of Cigarettes) can be found in the lockers. Then, head down to the other end of the corridor. We're almost out of this area.

As an aside, if you run into one of your dad's old friends, she'll tell you that she gave him up in the name of the Enclave's advanced scientific utilities. We gunned her down for good measure, but this will net in negative karma gain, so keep that in mind if and when you encounter her (and scour her room for more goods, especially of the curative nature). When you eventually find a well-guarded bedroom at the end of a corridor in the B sector, you know you're on the right track. You can down the barrier on the left side of the room by hacking a nearby computer if you so desire, grabbing the Buffout, Mentats, 10mm Rounds and more within the crates there. You can also find the ZAX Destruct Sequence, some Flamer Fuel and more. But ultimately, you'll want to use a nearby staircase running from the adjacent corridor up to a door that leads to the first level of Raven Rock.

Part 2

If it's not clear that there's a power struggle between Autumn and Eden by the time you get here, it will become clear once you arrive. Enclave Soldiers are gunned down by robotic sentries sent by Eden, who leave you alone. It seems John Henry Eden really wants to meet you, after all. But how does he have so much control over the robotic elements of the Enclave? You will soon find out.

Run forward down the corridor beyond where the Enclave soldiers were done in. This will lead to what appears to be a gigantic super computer that you can climb up. In fact, many staircases and catwalks will lead you higher and higher, further and further up, until you reach the top of the super computer. At this point, your first instinct will likely be running towards the door at the top of the stairs. But when you try to open it, you're unable to proceed. And then you hear John Henry Eden laugh and tell you to come look at him. But there's no one there! Wait just a minute...!

John Henry Eden, the president of the Enclave, the president of the United States, is a... a computer? Well my friends, you've now been exposed to one of the greatest secrets and spoiler points in the entire game. Congratulations! But now, it's time to engage this super-intelligent computer in conversation. It appears Eden has been alive and well since before the Chinese-US war destroyed the world. He was created for just such an occasion as a nuclear war, and has been ruling the Enclave and the remnants of the United States government for the better part of two-hundred years. We'll let you talk to him (at length) to get the rest of the information. And there's a lot of it. Keep in mind that your main objective after the conversation is over is to grab the FEV Vial before heading out the nearby door that was locked before. But with some persuasion and skill, you can convince Eden to destroy himself, which will make your escape from Raven Rock different than it would otherwise be. For the record, we here at IGN Guides convinced Eden through science that he must destroy himself. And he concurred.

It's time to make our great escape from the compound (which, for us, is being destroyed under our very feet since we convinced Eden to destroy himself). But President Eden is still very much plugged into the system, and his robotic Enclave friends will again assist you in getting out of dodge as quickly and as safely as possible. When you reach an office alcove, hack the computer if you can to free a powerful beast named Deathclaw, which you can then kill (as rapidly as you can) for massive experience. He packs a powerful punch, though, so be sure to down him as quickly and efficiently as you can! And comb the desk next to the computer for more items, including some healing items like a Stimpak.

Further down, the fray will intensify greatly. Gun turrets and mobile robotic units will do their best to nullify the human Enclave threat as much as possible (meaning, you shouldn't turn your ire on them as long as they're helping you), but they might not succeed in certain areas of getting rid of the threat completely, leaving a few half-damaged enemies for you to kill. Once they're dead, you can proceed forward, but be sure to check underneath the metal grating you're walking over via a staircase leading down, where a plethora of treasure chests lie in wait. Open them for all sorts of goods. Curative goods (Stimpaks, Dirty Water, RadAway, Rad-X and more) should be expected, but it's the myriad Plasma Mines, Plasma Grenades and Microfusion Cells that will really pique your interest.

Now, we're almost out of Raven Rock, but not quite yet. When you come across a light blue force field on your right as you're heading forward, you know you're headed in the right direction (though this entire area is completely linear, so getting lost shouldn't be much of an issue for you). There's going to be minimal help in taking out these last Enclave soldiers, and worse yet, they're decked out in powerful Tesla Armor and are toting, of all weapons, Missile Launchers. Quickly hack the computer so you can get through the force field. Grab the items you can (of most interest will be the Gatling Laser and Plasma Pistol), and then get ready to fight this final set of goons, concentrating on one at a time. The humongous amount of Stimpaks you've found (and likely already had) will come in handy here, since missiles do a number on your limbs. Take out these final foes and make sure to grab their Tesla Armor as you run outside.

The situation outside is hectic. You won't find any Enclave ground forces (thankfully), but if you were nice to the Super Mutant named Fawkes earlier in the game, he will be out here taking shots at the interesting helicopter craft the Enclave uses. Speaking of which, those helicopters are taking off en masse heading to an unknown destination. It seems like some sort of invasion force is brewing. What's going on!? Well, teleport instantly to the Brotherhood of Steel's stronghold at The Citadel to find out.

Once you arrive at The Citadel, you'll find it much the same way you left it when you took off earlier. But worry not, for even if things in the courtyard of the former Pentagon seem like business as usual, once you enter the building itself and head down into the laboratory, things are a little more hectic. Elder Lyons and her daughter, who heads the Brotherhood of Steel's elite unit (Lyon's Pride) are arguing over how to act next. And that's where you come in.

Until the Elder and Sarah begin talking to you directly, they don't know that the Enclave has the G.E.C.K. and can now effectively start Project Purity on their own at the Jefferson Memorial. Making matters worse, the Enclave has sent everything they had to protect that position and don't intend whatsoever to let it go without a fight. After either holding onto or giving away the FEV Virus (keeping in mind that the Brotherhood intends on destroying it after examining it), you'll be given an option by Sarah for some new armor (which you should decline, since you have Tesla Armor, much more powerful than whatever she's offering you). Then, when you're ready, speak to her again to begin the game's final mission.
